More correctly:

If I suspend by typing pm-suspend or echo mem >/sys/power/state, then it 
resumes just fine.  If I log in to Gnome and push the suspend button, 
then it does not resume.  This seems to be the case with or without your 
patch.

-rc8 and -rc9 with the original patch 4b4f7280 resume fine no matter how 
I suspend.
